Hi all,

I am using this software for RNAseq mutation analysis: https://github.com/davidliwei/rnaseqmut

My final output file is a VCF file and I want to convert it to a MAF file.

I have come across these posts,however the output VCF from RNAseq is a bit different in this case.

Converting Vcf File To Maf

Vcf To Maf (Mutation Annotation Format) Conversion ?

for example the annotation column has each Sample with 4 values namely reference allele reads and alternate allele reads Sample_6385_11.DP4=0,0,1,2

Any suggestions on how to get this data to a format like this?
